In their new film "The A-Team," Bradley Cooper and Jessica Biel share a memorable lip-lock as Face and one of his comely cohorts, Charisa Sosa. But as attractive as the prospect of a make-out session between these two very attractive actors might be, on Sunday night all eyes will be on the couple they present Best Kiss to at the 2010 MTV Movie Awards.

MTV Movies recently spoke with Cooper and Biel during interviews promoting "The A-Team," which hits theaters June 11. In addition to describing the challenges of bringing to life a big-screen version of the beloved 1980s television series, the actors each revealed their own secrets for creating a memorable onscreen kiss.

Cooper said that crafting a successful kiss has a lot to do with how it looks. "It's got to be hot, right?" he said. The actor has enjoyed his share of smooches in recent movies, with Leslie Bibb in "The Midnight Meat Train," Rachel McAdams in "Wedding Crashers," Sandra Bullock in "All About Steve" and both Jennifer Connelly and Scarlett Johansson in "He's Just Not That Into You." (That last one more or less makes him our personal hero.)

For Biel, meanwhile, the key to a great kiss has a lot to do with chemistry — and she means that literally. "Probably cherry lip gloss is a good ingredient," she revealed. "And maybe an Altoid." In addition to her recent smooch with Cooper, during her movie career Biel has shared sweet moments with Freddie Prinze Jr., Chris Evans, Nicolas Cage, Adam Sandler and Jamie Foxx. She admitted that her secrets to onscreen kissing were probably applicable to kisses in the real world as well, calling it good advice "in general, really."
